Unable to log into IMAP

[Chry Cheng]

Suddenly unable to log into my IMAP service.  I suspect it might be a network 
problem (e.g., unstable Internet connection) but would like to ask for second 
(or more) opinion.  Attached are the IMAP log and debug output with user name 
and password masked out.
